BACK AND ARM REST FOR FURNlTURE.

SPECIFICATION forming part of Letters Patent No. 457,125, dated August4, 1891.

Application filed April 16, 1891.

To all whom it may concern:

Be it known that I, WILLIAM LIESENBEIN, a citizen of the United States,residing at New York city, in the county of New York and State of NewYork, have invented certain new and useful Improvements in Back and ArmRests forFurniture; and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it a'ppertains to make and use the same.

This invention relates to an improved arm and back rest for furniture;and the object of my invention is to provide such arm and back rest soconstructed that it can easily be adjusted to have any desiredinclination, and

is automatically locked in place when thus adjusted.

The invention consists in the combination, with the bod y-frame of anarticle of furniture, of a pivoted rest on said frame, segmental rackssecured to said rest at the pivoted ends, pawl-rods engaging said racks,a rocking shaft in the frame, cams on said shaft adapted to act onspring-bars connected with the pawlrods, and means for turning saidrocking shaft.

The invention also consists in the construction and combination of partsand details, as wfill be fully described and set forth hereina ter.

In the accompanying drawings, Figure I is a plan view of the under sideof a lounge provided with an arm-rest of my improved construction. Fig.II-is a vertical longitudinal sectional view of the same, and Fig. IIIis a transverse sectional view on the line 3 3 of Fig. II. 7

Similar letters of reference indicate corresponding parts.

The body-frame A of the lounge is provided with the usual legs B, and atone end is provided 011 its top edges with the wings C, havingsemicircular recesses D, in which the rounded lower ends of the endpieces a of the head or arm rest E can swing, the pivots of said endpieces being mounted to turn in the plates F, secured to the innersurfaces of the side bars of the frame A, as shown in dotted lines inFig. II and in full lines in Fig. III. To the inner surface of each endpiece a of the rest E a segmental rack G is secured at serial No.389,124. (no model.)

the lower end, said racks being adapted to be engaged by thevertically-slidin g pawl-rods H, provided near their lower ends withnotches, into which the free ends of spring-barsJ pass, that are securedto the ledges J, fastened to the inner surfaces of the side pieces ofthe main frame A, said spring-bars J serving to press the pawl-rods Hupward and into engagement with the teeth of the segmental racks G. Atransverse shaft L is mounted to turn in the side pieces of the frame,and is provided at each end with a cam M, adapted to press thespring-bars J downward, and thereby pull the pawl-rods H downward andout of engagement with the teeth of the segmental racks G, thuspermitting of swinging the rest E onits pivots. An arm 0 (shown indotted lines in Fig. II and in full lines in Figs. Iand III) projectsfrom said shaft beyond the end of the main frame, so as to permit ofpressing the free end of said arm downward, whereby the shaft L isrotated slightly and the cams M press the spring-bars J downward.

To permit of turning the shaft L from either side of the sofa, the wiresor cordsPare fastened to the arm 0, and are passed around pulleys Q onthe under side of a cross-piece R of the main frameAand through eyes Son said cross-bar, and are provided on their ends with rings T or othersuitable handles. By pulling on either of said handles T the arm 0 ismoved downward, the shaft L is turned, and the cams M, acting on thespring bars J, move the same downward, whereby the pawl-rods II aremoved downward and disengaged from the teeth of the racks G. To bringthe rest E into a vertical position or to adjust it toward a verticalposition, it is only necessary to move the same in the direction of thearrow :0, Fig. 2, as the teeth of the pawls G are so shaped that theyslide over the beveled endsof the pawl-rods H, which pawl-rods lock therest in place as soon as it is released. When it is desired to lower therest E, the arm 0 must be pressed downward from the head end of thesofa-frame, or one of the handle-rings T must be pulled outward, so asto press down the arm 0. The headrest can thus be adjusted from eitherside of the sofa or from the end of the same. I lBackrests foreasy-chairs can be arranged in the same manner as the rest on the loungeshown.

Having" thus described my invention, I claim as new and desire to secureby Letters Patent- The combination, with a body-frame, of a pivoted reston the same, segmental racks on said rest at the end of the same,pawl-rods mounted to slide in the body-frame and engaging said racks,spring-bars connected with the pawl-rods, a rocking shaft on thebodyfranie, cams on said rocking shaft adapted to act on thespring-bars, an arm on said shaft,

and cords connected with said arm and passed over suitable pulleys onthe end of said arm and extending to the side of the body-frame,substantially as set forth. 15

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM LIESENBEIN. Witnesses:
